ADAPT-ABI - Special-purpose program for the design and analysis of prestressed concrete bridges built either segmentally or conventionally. It provides information for geometry and stress control during construction, as well as design values for service load.

Allplan - Nemetschek Allplan provides object-oriented planning and design software for architects and engineers. It enables users to create architectural and structure models, as well as obtain information on quantities and costs throughout all project phases. What makes this software special is that you can switch between 2D drafting and 3D modeling depending on the project phase or type. In this way, you can combine the best of both worlds and use the approach that suits you best at any time.

Archie-M - Archie-M is a Windows program (Windows NT/2000 and XP) designed to help with the analysis of masonry bridges and viaducts. It is based on the principle of the thrust line, but goes rather farther than that. It can be used as part of the assessment or design process.

Archie-M provides rapid, interactive equilibrium analysis of arching structures. The program is a result of nearly 20 years of research and consultancy.

Archie-M uses the zone of thrust to define the minimum structure necessary to support a given set of loads. Graphical and numerical results are updated continuously as loads are moved across the structure by hand or automatically. The engineer is able to explore the potential for different load paths to transmit loads to the foundations.

BASSIN - Legacy software from 1983 to compute three-dimensional dynamic response of an arbitrarily configured, elastic, bridge/abutment/backfill system. Source code in FORTRAN and related reports can be downloaded from the earthquake engineering online archive maintained by University of California Berkeley.

The BASSIN methodology has the following features: It computes the three-dimensional dynamic response of an arbitrarily configured, elastic, bridge/abutment/backfill system. It assumes this system to be underlain by a soil continuum that is represented as an elastic half- space. It represents seismic input motions as being harmonic and induced by planar P-, SV-, SH-, or Rayleigh waves with arbitrary wavelength, amplitude, and direction of incidence. The methodology uses a substructure approach in which the structure (which comprises the bridge, abutment, and backfill) is represented using a three-dimensional finite element model, and the underlying soil continuum is represented using a boundary element approach. The finite element model defines the stiffness matrix, mass matrix, and fixed-base nodes for the structure. The boundary element approach characterizes the underlying soil medium using frequency- dependent impedance matrices and driving force vectors that also incorporate the free-field wave motions. Compatibility and equilibrium requirements at the soil/structure interface are used to couple these substructures. The steady-state response of the soil/structure system is then computed.

CELL4 - Legacy software from 1985 which based upon the finite element method and is particularly suited for the analysis of post-tensioned box girder bridges of constant depth which have arbitrary plan geometry and support conditions. Source code in FORTRAN and related reports can be downloaded from the earthquake engineering online archive maintained by University of California Berkeley.

Department of Civil Engineering, University of California, Berkeley, 1985,

CELL4 is a program based upon the finite element method and is particularly suited for the analysis of post-tensioned box girder bridges of constant depth which have arbitrary plan geometry and support conditions. The bridge can be straight, curved, or quadrilateral in plan. The longitudinal interior webs must be vertical, but the longitudinal exterior webs can be vertical, sloping, or curved. Transverse diaphragms can be modelled by vertical web elements or by special web elements in regions with sloping or curved webs. The top and bottom deck slabs as well as the interior and the exterior webs may be prestressed. Boundary conditions at any nodal point are arbitrary, allowing rigid supports as well as translational and rotational elastic supports, oriented in any arbitrary direction to simulate the stiffness of the supporting columns and bents. For prestressing analysis an automatic input has been provided to define the geometry of the two types of post-tensioned unbonded tendons which can be used. Each panel or slab tendon can be stressed either from one end or both ends, and losses due to friction and anchorage slip are accounted for. In order to facilitate the interpretation of output, an automatic integration of internal forces to give individual girder and total sectional force resultants is incorporated. This permits a better understanding of the load carrying mechanism in a complex bridge system, and can also be used to carry out equilibrium checks easily.

Concise Beam - Concise Beam is an easy to use Microsoft Windows based program for the design of precast concrete beams. Concise Beam will perform a load analysis and design checks in accordance with the latest edition of ACI 318, CSA A23.3 or AS3600. CSA S6 is also supported without moving loads. Key code parameters can be customized to simulate other design codes. The beam can be conventionally reinforced and pretensioned. It can model any cross-sectional shape and will allow the cross-section to vary prismatically (step-wise) over the length of the beam. A graphical editor allows the user to describe any cross-section, including voids, openings or cut-outs.
Concise Beam currently works in two-dimensions but will also account for torsion along the beam. The user can work in metric or Imperial (US Customary) units, select from a variety of individual units (i.e. mm, cm, m), and switch back and forth at will. Libraries of industry standard cross-sections and materials are provided with Concise Beam. The standard libraries can be modified, extended and customized by the user.

FB-MultiPier - The FB-MultiPier analysis program is a nonlinear finite element analysis program capable of analyzing multiple bridge pier structures interconnected by bridge spans. The full structure can be subject to a full array AASHTO load types in a static analysis or time varying load functions in a dynamic analysis. Each pier structure is composed of pier columns and cap supported on a pile cap and piles/shafts with nonlinear soil. This analysis program couples nonlinear structural finite element analysis with nonlinear static soil models for axial, lateral and torsional soil behavior to provide a robust system of analysis for coupled bridge pier structures and foundation systems. FB-MultiPier performs the generation of the finite element model internally given the geometric definition of the structure and foundation system as input graphically by the designer. This allows the engineer to work directly with the design parameters and lessens the bookkeeping necessary to create and interpret a model.

ISADAB - Legacy software from 1986 for the transverse inelastic analysis of reinforced concrete highway bridges. Source code in FORTRAN and related reports can be downloaded from the earthquake engineering online archive maintained by University of California Berkeley.

ISADAB was developed for the transverse inelastic analysis of reinforced concrete highway bridges. The following tasks can be carried out by the program: (a) static analysis, (b) free-vibration analysis for initial displacements caused by static loads, (c) frequency analysis based on instantaneous stiffness during static loading, and (d) earthquake response analysis. The nonlinear effects are accounted for by incorporating translational and rotational springs at abutments, pier foundations, and at the base of piers. The deck and piers are treated as line elements. Two hysteresis models are used to represent the cyclic behavior of the nonlinear components: the Ramberg-Osgood model (for abutment springs) and the TQ-Hyst model (for pier and foundation springs), which operates on a tri-linear primary curve.

LAPBOX - Legacy software from 1986 for the analysis of curved nonprismatic reinforced and prestressed concrete box girder bridges. Source code in FORTRAN and related reports can be downloaded from the earthquake engineering online archive maintained by University of California Berkeley.

LAPBOX: Linear Elastic Analysis of Box Girder Bridges

Choudhury, Deepak

Department of Civil Engineering, University of California, Berkeley, 1986,

LAPBOX is an implementation of a numerical procedure for the analysis of curved nonprismatic reinforced and prestressed concrete box girder bridges. Thin-walled beam theory and the finite element method are combined to develop a curved nonprismatic thin-walled box beam element. The cross section of the element is a rectangular single-cell box with side cantilevers. The axis of the element is curved in plan. The cross sectional dimensions vary along the element axis. Eight displacement degrees of freedom, including transverse distortion and longitudinal warping of the cross section are considered at each of the three element nodes. Small displacements and small strains are assumed in the element formulation. Prestressing, consisting of post-tensioned bonded tendons in the longitudinal direction, is considered. The tendons are idealized as straight prestressing steel segments between nodes of the box beam elements. Friction and anchorage slip losses are considered.

Pro/Bridge Geometry - Pro/Bridge-Geometry is a versatile bridge modeling system that enables engineers to use the basic geometric parameters of road surface and bridge components to capture the complete 3-D geometry of a simple or very complex bridge site.

The system provides solutions to complex geometric problems that are difficult to do by hand, time consuming and tedious in nature. Such problems are often prone to errors that could lead to serious cost overrun and legal liability issues. It removes the geometric limitations in the design process and allows exploring better solutions to complex bridges.

Starting from the digital terrain data, basic alignment and road data, the user can dynamically manipulate the basic parameters that control the layout and proportioning of bridge elements. The effect of any parameter change is propagated into the complete 3-D model and instantly updates screen views as well as all tabular and graphic reports. The system accounts for the variety of bridge types and component shapes.

The system generates tabular reports such as screed elevation table and graphic reports as well as drawings such as abutment, piers, footing layout, girder layout, etc. Output can be viewed, printed and/or exported to packages such as AutoCad or Excel to finalize the generation of contract documents.

The system is not a bridge analysis or design program nor is it intended as a replacement of CAD packages such as AutoCAD.

RM2006 - 4D static and dynamic design and analysis of concrete, steel and composite structure. Can be used to investigate any bridge type and erection sequence. Incoporates 14 international design codes.

RiverCAD - RiverCAD is a sophisticated river modeling software than can be used for evaluation of bridge scour.

The software was developed in cooperation with several major engineering companies involved in FHWA and DOT bridge replacement contracts to completely automate the FHWA HEC 18 bridge scour calculations and analysis, design, and reporting necessary for bridge replacement and armoring projects. RiverCAD will analyze a bridge for scour and create a "ready-to-submit" FHWA-accepted bridge scour engineering report in just minutes. The scour report includes all input data, equations, variables, intermediate results, final analysis results, and analysis narrative - along with placing the computed scour results directly on the bridge within the AutoCAD drawing.

SOFiSTiK is one of the most complete FE packages and covers almost all structural engineering disciplines: building, bridges, foundation, tunneling, membranes, lightweight, dynamics. Design code checks can be performed for 18 international codes.

UTrAp - UTrAp is a software package developed for pour sequence analysis of curved, trapezoidal steel box girders. Single and dual girder systems with a constant radius of curvature can be analyzed with this program. The software consists of a Graphical User Interface (GUI) and an analysis module. The analysis module relies on the finite element method to compute the response of a three-dimensional bridge structure. Input data is supplied to the program through use of a GUI. The program can handle multiple analysis cases and has graphics capability to visualize the output.
It also offers the capability of performing an eignevalue buckling analysis, and it allows for exporting results to Excel.
